Can't reinstall iTunes on Windows 7 64 bit machine, tried everything

10-11  Source: Network gathering  Views:1 

Hi, I've followed the threads fromb noir and others with similar errors and 'no joy'   Here is my situation:
I have a windows 7 64 bit machine that I upgraded from Windows XP.  I upgraded about a year ago, no problem.  I got an iPhone (love it) and was synching to my windows machine for months, no problems.  Not sure what the trigger was (think it was an iTunes SW update) but I started getting error messages and the phone would no longer synch.
I uninstalled itunes, then when I tried to reinstall I got different errors.  I googled the error message and related ones, and tried the following:
- I ran the fix for Windows Update. It said it resovled problems, but it is still behaving strange.  It shows successful updates, but when I ask it to check for new updates, it just keeps looking and never completes.  In the background, it appears to be actually making updates which it shows as successfully installed.
- I updated the C++ redistributable package and the .NET package from the MSFT website.
- I've uninstalled all the components of Apple several times, tired the trick of deleting the previously downloaded components and updated manually, etc.
Here is the first message I get when I try to install Itunes64Setup.
An error occurred during the installation of assembly "Microsoft VC80.CRT,type="win32",version = "8.0.50727.6195".publick key token = 1fc8b3b9ale18e3b.processor architecture = "x86". Please refer to help and support for more information. HResult:0x8007002
Appreciate any help or guidance - hoping to avoid having to reinstall Windows again.
Can someone please respond to my request for support?  I tried the provided correct answer at  but it did not work. 
I also got a MSFT tech support person to remotely look at my machine, for what its worth, he said the registry file is fine and to contact Apple support.
Any help would be very much appreciated.
